What Happened to Outlook Online's Reply Button?

Microsoft seems to be constantly updating Office Online, and that's nice, but one recent change has annoyed me slightly. It appears that Reply is no longer accessible with one click from the normal message view. It used to be right in the menu bar, but that area seems to have been repurposed for navigation and categorization. There is a small drop-down menu off to the right with Reply All as the default, but I almost never want to reply to everybody who received the message. (Bedlam DL3 ahoy!) Pulling that menu down produces Reply as the first option, but using it doesn't make it the default action for the button/menu.

May I have the Reply button easily accessible again, please?
